the workings behind the Citizen Eco Drive ...

Very interesting, Panos. My brother has one of these, so now I can talk intelligently to him about his watch. I assume that the cell that stores the power will ocassionally need changing as it becomes less efficient - just like rechargable batteries.

My brother also bought one of those. It was his fill-in look-alike to an Explorer 2. He paid $81 and said it was not the fill-in substitute to a Rolex he thought it would be. He went back to using his LV Sub for daily use.

Apparently I remembered his email to me incorrectly and got it 175 deg off base. Here's his note to me on his Eco-drive:

"I received my new Citizen Eco-Drive. The watch is noticeably lighter than my Kermit, and mechanically inferior, which is obvious when making adjustments, but $81 versus $6500 allows for this. Overall the watch is what I expected, but what surprised me was the lume… although weak compared to a Rolex… is BLUE!.. and looks really COOL! The design is Military but smallish which makes this watch ideal for me. It doesn’t overwhelm my wrist like other watches like my G-Shock! It’s light weight and analog dial makes it the perfect work watch for me. The band is exceptionally durable… another surprise."

Ha, Ha...I guess I've got the wrong model:

"Eco-Drive's revolutionary Eco-Drive Energy Cell stores enough energy to power the watch up to an astonishing 5-years (depending on model) even in the dark."

Really? Like I said, I guess I've got the wrong (read: 'lemon') model. I bought a few chrono versions years ago when I was a teenager...they work extremely well, but I've never had the watch run very long unless it gets daily sun light exposure.

i own a Titanium Citizen Chrono perpetual calendar, it is a very good watch, it has alarm, chrono, you can set a time for otrher country or city if you travel a lor you just change to LTM and will have another time, it has perpetual calendar witch you never have to move the date when a month is a 30 day month or Feb is a 28 days, you set the watch for the current year and the chip knows if that year feb has 28 or 29 days.
is a very good watch and its a divers watch also.

There are a lot of those, it seems. You'll see Eco-Drives dirt cheap on Ebay/Craigslist/Propertyroom because they quit working.

what the watch needs is a solar panel on the face

That's what it is. Its a solar panel under a partially transparent face that lets in some light. It doesn't take much to trickle charge a watch battery.

Household solar panels are rated to last 20 years and will give pretty good power for 25-30 years before they degrade.
